NORTH AMERICAN FAUNA. 



General remarks. — Without seeiug the South American species orig- 

 inally associated \Yith D. intermedius by Peters, it is impossible to 

 determine whether these belong in the genus as now understood.

Type ?oc«/if?/.— Matamoras, Tamaulipas, Mexico. 

 Geocjraphic (listrihufion. — Gulf States and northeastern Mexico. 

 General characters. — Size, large (forearm, 45-56) j color, light brown. 

 TJars. — The ears are short, reaching barely to nostril when laid for- 

 ward. The dorsal surface is densely furred on basal half, but other- 

 wise tlie ear is naked except for a sprink- 

 ling of hairs on inner side, esi)ecially along 

 anterior edge. Beginning at lower edge 

 of basal lobe the anterior margin is first 

 strongly convex, then nearly straight for 

 a distance of about G mm., then abruptly 

 convex (or even angular), after which it 

 continues nearly straight to narrowly 

 rounded off tip. Posterior border slightly 

 concave immediately^ below tip, then 

 gently and evenly convex to notch above 

 posterior basal lobe. Posterior basal 

 lobe well developed, slightly notched on 

 lower side, and joining face about 5 mm. 

 behind angle of mouth. 

 Tragus blunt and bent forward, anterior

 ^^'^^^^^-■'> just below tip. Posterior border convex 



immediately below tip, then straight to point opposite anterior base. 

 Here a sharp angle is formed, below which the margin is irregularly 

 crenulated to base. 



Feet. — The foot is moderate in size, a little less than half as long as 

 tibia. Calcar slightly shorter than tibia, very indistinctly keeled and 

 terminating obscurely^ or in an ill-defined lobe. 



Membranes. — Membranes thick and leathery. Wing membrane at- 

 tached at base of toes, uropatagium near tip of last caudal vertebra. 

 Free border of uropatagium slightly longer than calcar. 



Fur and color. — The fur is full and soft. On the middle of the back 

 it is about 12 mm. in length. The fur of the back extends on basal half 

 of outer side of ear, basal half of dorsal surface of interfemoral mem- 

 brane, and base of wing membranes. On the latter it occupies a strip 

 about 10 mm. in width. There is a slight tuft of bair at the base of the
